HelioIndex: comparison of countries for authors' first and last papers
The table below compares the numbers of authors in each country based on their first and last papers. This gives an indication of the movement of scientists within the field.
A positive percentage means there has been a net migration out of the country, and a negative percentage means there has been a net migration into the country.
Note that if the ORCID record for an author is incomplete, then the first paper affiliation is likely to be incorrect.
